Hi @daffl
Oauth in our project suddenly broke, and it turned out that we use cookie-session for OAuth like so

const cookieSession = require('cookie-session');

  app.configure(expressOauth({
    expressSession: cookieSession({
      name: 'session',
      keys: ['grant'],
      maxAge: 60 * 1000
    })
  }));

that fixes OAuth when scaling the app Kubernetes. So now when trying to authenticate, it throws an error because cookie-session doesn't have destroy.
The bug is in authentication-oauth repo.

Thank you.
